Transmission Components

Operating line pressure is the lifeblood of any automatic transmission by providing the clampingforce on the clutches and bands. Oftentimes, increasing line pressure is a requirement whenincreasing driveline output. The new TCI® 4L60E boost valve assembly provides you the meansof elevating your line pressure while also addressing wear issues that may actually have yourtransmission running at a lower level of pressure than GM intended.

Boost valve features: larger diameter over stock that yields 10-15% higher line pressure, o-ringson boost sleeve which prevents loss of boost signal pressure, sleeve constructed from AlcoaDeltalloy 4032 & hard-coat anodized which prevents wear between the mating parts.
